    I know a 556 timer for a cpu is crappy, but it works. I've put about an hour and a half of work into it.

    Features:
    Keyboard (not done)
    Mini LED Screen
    Can display numbers

    Working on:
    LCD Screen

    Whats Hard:
    So I am going to need a real cpu if I want any chance of an OS. Planning on using the zilog z80 to power it. Once I do that I want a 'very' small version of DOS, or some kind of command line.

    Problem: Uses too little power. Need to stop using powerful resistors. ANY REPLYS?
